EYEG LASS NOSE-GUARD.

SPECIFICATION forming part of Letters Patent No. 710,594, dated October'7, 1902.

Application filed April 18, 1901. Serial No. 56,370. (No model.)

To (all Iv/ 7,0772 it inmy concern:

Be it known that I, EMIL B. MEYRowrrZ, a citizen of the United States ofAmerica, and a resident of the city of New York, in the State of NewYork, have invented a new and useful Improvement in EyeglassNose-Guards,of which the following is a specification.

This invention relates to eyeglasses, and has special reference to themeans for retain- 10 ing eyeglasses upon the nose of The wearer. Thedevices commonly used for this purpose are known as the guards and thebowspring, the latter pressing the guards against the opposite sides ofthe nose, which thereby I5 act as clamps. The guard is usually facedwith shell, cork, or other similar holding material. In order that theguard may take hold of the nose at the proper place, it is oftennecessary to ofiset the guard from the post or frame to which it isordinarily attached and to position the guard at more or less of anangle to the plane of the lenses. One of the most common forms of guardis merely an elongated narrow plate, which affords large bearing-surfaceand at the same time can be readily set at any desired angle to thelenses. In order to offset this form of guard from the post, it isnecessary to connect it with the post by a supporting-arm, and this armnaturally occupies an angular position with respect to the guard. Ifthis supporting-arm could itself be used as a guard, it would materiallyaid the main guard in holding the glasses on the nose, because, owing toits angular position with respect to the main guard,

it would serve as a brace or steadying element, the contact against thenose being then along two intersecting lines instead of along the oneline of the guard. It is the object of my invention to utilize thissupporting-arm of the guard as a steadying element in aid of the mainguard; but in order to do this without sacrificing the adjustabilitydesirable in the arm I leave the face of the arm naked- 2'. 6., I omitthe shell facing-and make the arm of malleable material, so that itsshape and direction can be readily determined by the aid of the pliers.

Broadly considered, my invention therefore consists in the combination,with a guard provided with the usual shell or other bearing-surface, ofa supporting-arm connecting the guard with the post or eyeglass-frame,said arm being so shaped and directed as to bear against the nosethroughout substantially its entire length. To carry out this idea, itis necessary, among other things, to offset the supporting-arm at thepoint where itjoins the metallic portion of the main guard in order tobring the surface of the arm into line with the surface of the shell orother bearing material on the main guard. It is also necessary to givesuch a direction to the arm that it will continuein contact with theside of the nose until it enters or engages the post.

I am aware that guards have been made heretofore which were supportedfrom the post by an arm and which arm was offset to form a seat at itsextremity for the guard; but such offset was not for the purpose ofbringing the arm into contact with the nose, nor could such contact havebeen obtained unless the direction of the arm was made to agree with theshape of the nose. As a matter of fact such arms as have been usedheretofore were merely connectors between the guard and the post, andtheir ofl'set was solely for the purpose of seating the guard in the armor directing the latter properly to the post, and hence possessedneither the function nor the construction of my improved guard.

The accompanying drawings illustrate my improved guard.

Figure 1 is a perspective back view of a pivot-guard made according tomy Patent No. 572,306, dated December 1, 1896, and provided with thepresent improvement. Fig.

2 is a face view of the same. Fig. 3 represents an enlarged section onthe line 3 3 of Fig. 2. Fig. 4 is a perspective back view of anotherform of nose-guard embodying the improvement. Fig. 5 is a face viewthereof. Fig. 6 is an enlarged section on the line 6 6 of Fig. 5, andFig. 7 is a plan showing the 5 position of the glasses and my improvedguard upon the nose.

The two forms of nose-guards illustrated are indicated by A and B,respectively. The guard proper consists of the metallic elon- I00 gatedplate 2, having fixed to its front face a strip of shell, cork, or otherholding material 1, which is held thereto by means of rivets 3 and 4 orin any other manner. This guard is supported from the usual posts f,which carry the lenses, by means of an arm a, one end of the arm havinga hole I) for the passage of a screw, which enters the post, and theother end leading to and connecting with the metallic portion of theguard at any point along its length. The arm may be either integrallyconnected with the metallic part of the guard or it may be fastenedthereto by the rivet 5 or in any other manner. At all events the armserves as the connecting-link between the post and the guard and standsat an angle with the guard throughout all or a portion of its length.The guard is by means of this arm a offset from the post and thrown outof the plane of the lenses. It may also be made to occupy any positionwith respect to such plane by changing the angle between the arm and theguard. To furnish a steadying element in connection with the guard, Ishape and direct the arm a in such a manner that it will bear againstthe nose throughout nearly its entire length from the point where it isattached to the guard to the post. A portion of this shaping consists inoffsetting that part of the arm closely adjacent to the guard, as shownat 0, so as to bring it flush with the face of the shell orbearing-surface on the guard, and from this point the arm is so shapedas to remain in contact with the nose until it enters the post f, asclearly shown at r Fig. 7. In some cases it may be necessary to curvethe arm a so that its bearing-surface will follow the surface of thenose, and in order to readily make these adjustments I prefer not to useshell or other bearing material upon the arm, but leave the same nakedand use malleable or pliable metal which will retain any shape given toit by the pliers.

Havingdescribed my invention, I claim 1. In eyeglasses, a guardconsisting of a plate having attached to it suitable material affordinga bearing-surface, in combination with a naked supporting-arm by whichthe guard is attached to the glasses, said arm being of malleable metaland conforming in shape with, and adapted to bear against the nosethroughout substantially its entire length.

2. In eyeglasses, a guard consisting of an elongated plate havingattached to it suitable material aifording a bearing-surface, incombination with a naked supporting-arm by which the guard is attachedto the glasses, said arm being of malleable metal and occupying anangular position with respect to the plate and conforming in shape with,and adapted to bear against the nose throughout its entire length.
